ABSTRACT

A combined structure made of a foam material includes a top panel, two long side panels, two short side panels, and a bottom panel, wherein the top panel at its bottom has a plurality of slots, and the long side panel at its top has two protruding tenons for engaging the slots, and the long side panel includes two penetrating groove holes on both sides for embedding the protruding tenons, and the long side panel at its bottom has a plurality of protruding tenons for fixing the slots at the corresponding positions at the periphery of the bottom panel. The foam material forms a table or a chair capable of storing articles, so as to achieve the effects of providing a convenient and quick installation, a light weight, an easy storage, and a feature of not occupying too much space after the combined structure is disassembled.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a combined structure made of a foammaterial, and more particularly to a combined structure comprising a toppanel, two long side panels, two short side panels, and a bottom panelto form a table or a chair, and the panels can be lifted for containingarticles, so as to achieve the effects of providing a convenient andquick installation, a light weight, an easy storage, and a feature ofnot occupying too much space after the combined structure isdisassembled.

2. Description of the Related Art

In outdoor barbeque activities, we need to prepare a dining table andchairs for placing food and providing seats, in addition the preparationof food. However, the portable table and chairs are usually made ofwood, plastics, or aluminum. Although the present material can be foldedand stored conveniently, yet wood is considered too heavy, plasticscannot carry heavy loads, and aluminum is too expensive. Furthermore,tables and chairs made of wood, plastic, and aluminum are still heavyfor transportation.

Further, the tables and chairs made of these materials are not suitablefor indoor uses such as a classroom with many children. There is alwaysa risk for children to accidentally bump into the hard tables or chairsand get hurt.

SUMMARY OF THE INVENTION

In view of the foregoing shortcomings of the prior art, the inventor ofthe present invention developed a combined structure in accordance withthe present invention to overcome the current technical problems.

Therefore, it is a primary objective of the present invention to providea combined structure made of a foam material that comprises a top panel,two long side panels, two short side panels, and a bottom panel, whereina plurality of slots is disposed at the bottom surface of the top panel,and the long side panel has two protruding tenons protruded from the topof the long side panel and embedded into the slots of the top panel, andthe long side panel has two penetrating groove holes disposed on bothsides of the long side panel for embedding and fixing the protrudingtenons on both sides of the short side panel, such that the size of thefoam material is used to combine a table or a chair, so as to achievethe effects of providing a convenient and quick installation, a lightweight, an easy storage, and a feature of not occupying too much spaceafter the combined structure is disassembled.

Another objective of the present invention is to provide a combinedstructure made of a foam material, wherein the long side panel includesa plurality of protruding tenons disposed at the bottom surface of thelong side panel for embedding and fixing the same quantity ofcorresponding slots disposed at the periphery of a bottom panel andreinforcing the whole structure of a foam material for its the supportfor heavy loads.

A further objective of the present invention is to provide a combinedstructure made of a foam material, wherein the long and short sidepanels include a bottom panel thereunder, so that when the top panel islifted, a function for storing articles is provided.

Another further objective of the present invention is to provide acombined structure made of a foam material, wherein the top panel is ina square shape, a rectangular shape, a circular shape, an ellipticalshape, or various shape having a curve along its periphery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1, 2A and 2B, a combined structure made of a foammaterial in accordance with the invention comprises a top panel 1, twolong side panel 2, two short side panel 3, and a bottom panel 4, whereinthe bottom of the top panel 1 has a slot 11 and the top panel 1 is in asquare shape, a rectangular shape, a circular shape, an ellipticalshape, or any other shape having a curve along its periphery, and thetop of the long side panel 2 has two protruding tenons 21 and a groovehole 22 separately disposed on the upper and lower positions of the bodyof the long side panel 2 and a plurality of protruding tenons 23 at thebottom, and both upper and lower position of the short side panel 3separately include a protruding tenon 31, and the periphery of thebottom panel 4 has a plurality of neatly arranged slots 41.

Therefore, the groove holes 22 at the upper and lower sides of the longside panel 2 are embedded and engaged to the protruding tenons 31disposed at the upper and lower sides of the short side panel 3, andthen the two protruding tenons 21 at the top of the long side panel 2are fixed into the corresponding slots 11 at the bottom surface of thetop panel 1, and the plurality of protruding tenons 23 at the bottom ofthe long side panel 2 are embedded and engaged to the plurality of slots41 at the corresponding positions around the periphery of the bottompanel 4, so that the foregoing foam material can be used to form eachpanel, and a larger sized foam is used as the top panel for a table andthe smaller sized foam is used as the top panel for a chair as shown inFIG. 3. Such arrangement provides a convenient and quick installation, alight weight, and a feature of not occupying too much space after thecombined structure is disassembled. Therefore, the combined structure ofthe invention can be moved easily for outdoor uses, as well as indooruses. Since the combined structure is made of a foam material, thereforechildren will not be injured when bumped into the combined structure.

Since the bottom of the long side panel 2 includes a plurality ofprotruding tenons 23 to be embedded and engaged to the slots 41 at theperiphery of a bottom panel 4, therefore it can reinforce the whole foamstructure for the support of a heavy load. In addition, the top panel 1can be lifted for storing articles such as toys and other things asshown in FIG. 4.

In summation of the above description, the present invention definitelycan achieve the expected effect, and the disclosed structure hereinenhances the performance than the conventional structure and furthercomplies with the patent application requirements.
